• Hi Anish, here is my title+abstract: Title: WIMPs and New Physics Interpretations of the PTA Signal are Incompatible
  Abstract: In order to explain the large amplitude of the nano-Hertz stochastic gravitational wave background observed in pulsar timing arrays (PTA), primordial sources must be particularly energetic. This is correlated to the generation of large density fluctuations, later...
